body 43, having the inclined recess 44, the lock abutting member 45 and the latch moving member 46. The removable locking member 43 carries the exteriorly annular boss 47 which is interiorly of angular formation and which extends through the opening 48 of the The lock operating means comprises two annular members 49 and 50 movable through the openings within the front 11. v.The interior portions of these two members 49 and 50 are pivotally connected by the yoke 51 having the extended locking tongue 52 and carried revolubly byY theV screw 53 threaded into the bottom l0. A n c g Slidable along the outer face of the two locking members 33 and '43 is a lock catch which ,comprises the body 54having the eX- tended locking Varms 55 and 56 and the recess 57. Y

The means for operating the lock comprises two angular bars 58 and 59, the bar 58 vhaving an extended threaded end 60, threaded into an opening within the bar V59, the two bars 58 and 59 being spaced, so that `either canbe turned without imparting movement to the other. The bar 58 extends into `the opening of the boss 47 and the bar 59 Aextends into the opening of the boss 3l. Each bar hasl a handle, or knob, (not shown) as its extended end.A The operation of the device is as follows When the device is in the position shown in Figure l, with the lock operating member 49 pushedinwardly, the lock catch is in such a position that the locking arm 56 abuts upon the butment-2l and the lock abutment mem- -ber 45 and it is evident .that the barV 59, which carries the outward knob cannot be revolved and hence cannot be usedl as a means for moving `the latch 26.` The locking Vmember 33, however,l can be moved as its-latch moving member 36 is capable of movement within the recess 61 ofA the lock catch and hence the bar 58 carrying the inward knob can be revolved, operating the latch 26.

n mechanism, and allow bar 59 to operate the Itis evident that simply reversing the lock catch 55-56 and bringing the members'-54, 54 upwardly will reverse the lock operating lock and prevent bar 58 from operating it. Itis to be further noted that the latch may .be 'readily reversedby drawing it inwardly releasing it from'the front 11 andreplacing it in reverse position.

If the latch operating member 50 be pushed inwardly, the locking tongue will move the mechanism into the position shown in Figure 2. The slidable lock catch 54 has lnow moved so that the locking arm 56has -moved from-abutment 2l and 45, and the latch may be operated by the revolution o i either bar 58 yor 59.

f VIt will be further notedthat by simply re- `ing ofthis tongue.

Ido not limit myself to the particular size, shape, number 'or arrangement of parts as .shown and described as these are given simply as a means for clearly describing my inventicn.V
